The keyways 42 will slidably receive Figure 10 is a horizontal sectional view taken the side edges of a plate having an u ta 3 eye (not shown), whereby the core may be lifted or lowered by a crane attached to the eye.

In use of the invention a plurality of the cores l and their associated liners 34 are used in order to form a retaining wall of predetermined length. A framework F is assembled and includes guides G that will engage and guide the liners 34 asv the same are driven into the ground. M A pair of liners 34 are disposed as shown in Figure 1 and a core is lowered therebetween until the flanges 30 engage over the upper ends iii the liners. Then a jet pipe P is extended downwardly through the bore 12 to wash away the ground as the core and its liners are moved downwardly into the ground. An additional driving force in the form of the hammer H is employed for driving the core and its liners into the ground. The bore 12 is filled with a filler 44 which is held in place by a dowel (not shown) and a lifting eye (not shown).

After a suitable number of the cores and their liners having been driven into the ground with adjacent cores and adjacent liners contacting each other, reinforcing rods R, if required, are inserted in the bore 24 and these rods are driven into the ground to remain in position as the cores are raised.

The filler 44 of the first core is raised and then the first core is lifted upwardly by a crane and as the core is lifted concrete is poured into its opening 32 to replace the core as the latter is pulled upwardly. After the first core has been lifted and removed the crane is shifted to lift the second core while concrete is still poured into the space previously occupied by the first core.

Concrete C being poured into the space previously occupied by the first core will move into the space vacated by the second core as the second core is lifted. Next the third core is lifted and concrete is poured onto the concrete previously poured so that the concrete may occupy the space left by the third core. The cores are thus lifted in the sequence they are driven with concrete poured into the space vacated by the cores adjacent the one being lifted. The last pour of concrete for the day will receive a vertical pipe or rod R0 that will form a key for the next days pour. Thus, the last core will have a vertical recess Re to receive the rod R0 and the initial core to be driven will have a recess Rx to accommodate the rod R0 (Figure 13) The cores may be shaped to form the tiein-- keys for uniting the pours of different days or for centering adjacent cores. Figure 12 shows interlocking tongues T and grooves Gr of V-shaped formation and Figure 13 shows the interlocking tongues Ta and grooves Ga of substantially channel shaped formation.

In starting the wall construction, the initial core will be engaged with an existing wall. struc- 4 ture, however, if the wall to be erected is incapa ble of being joined to an existing wall, then the liners of the first core are joined by a closure partition.

After the concrete has been poured into all the spaces previously occupied by the cores and the concrete has set the liners 34 are extracted and reset as shown in Figure 1. The bond between the liners 34 and the concrete is broken by driving a wedge between them with hammer H. Next the liners 34 are partly extracted two' at a time by pulling, the pulling force comprisin a, crane attached to a' lever which will grip the liners 34 and is engaged to them by rods through the arms 36. The extracting of the liners 34 is assisted with the use of water or air jets.

Having described the invention, what is claimed as new is:

1. Apparatus for constructing retaining walls, said apparatus consisting of a plurality of vertical cores, a pair of spaced parallel liners engaging opposite walls of the cores, and means attached to the cores removably engagin the upper ends of the liners, whereby a core and its liner may be driven into the ground and whereby the cores may be lifted from the liners, said cores having side openings in their upper ends adapted to accommodate the discharge chute of a concrete filled hopper.

Apparatus for constructing retaining walls, said apparatus consisting of a plurality of vertical cores, a pair of spacedparallel liners engaging opposite walls of the cores, and mean attached to the cores removably engaging the upper ends of the liners, whereby a core and its liner may be driven into the ground and whereby the cores may be lifted from the liners, said means comprising a pair of overhanging gripper flanges, and a header plate for the upper end portions of the cores to which the flanges are attached.

3. Apparatus for constructing retaining walls, said apparatus consisting of a plurality of vertical cores, a pair of spaced parallel liners engaging opposite Walls of the cores, and means attached to the cores removably engaging the upper ends of the liners, whereby a core and its liner may be driven into the ground and whereby the cores may be lifted from the liners, each of said cores having longitudinally ofiset side portions, said ofiset side portions having vertical bores for receiving reinforcing rods.
